Candle Raw Material Inventory Planning for Small Manufacturers

What an inventory plan actually is

Most small manufacturers have a stock list and call it a plan. A stock list tells you what is on the shelf today. A plan tells you what should be on the shelf, why that quantity and not another, and what it costs you to be right. The difference matters because inventory is the largest discretionary use of cash in a candle business after equipment, and it is the only one that can be adjusted every fortnight.

A working plan has seven material lines and four columns. The lines are wax, fragrance broken out by scent, wicks, wick stickers, vessels, care stickers and colour. The columns are monthly usage, cover in weeks, the pack you buy in, and the cash that cover represents. Everything else — the reorder trigger, the festive uplift, the dead-stock review — hangs off those twenty-eight boxes. If your plan needs a second page, it is probably tracking things that do not change your buying.

The plan also has a hard boundary, and it is worth setting it before the arithmetic starts. CSI sells raw materials, so raw materials can be priced here from live stock. Cartons, mailers, printed labels, ribbon, courier and freight, labour, electricity, rent, marketing and payment fees are all real costs of manufacturing candles, and none of them is something CSI sells or publishes a rate for. They appear in this plan as blank rows. Not as estimates, not as typical figures — blank, for you to fill from your own invoices. A plan with an invented number in it is worse than a plan with a gap, because you will trust it.

Step 1 — The monthly bill of materials at your output

The example running through this page is a small manufacturer pouring in two sizes: a 150 g fill in a Black Glass Jar with Black Lid and an 85 g fill in an 85 gram tin, split 70:30 by volume, at an 8% fragrance load of wax weight across three scents. That is the CSI convention — loads are stated as a percentage of wax weight on the product pages — and it means 12 g of oil in the jar and 6.8 g in the tin. Three output levels are shown because the plan changes shape, not just scale, as you grow.

Two numbers in that table deserve attention. First, the per-candle material cost is ₹254.99 for the 150 g jar and ₹158.66 for the 85 g tin — a difference driven as much by the vessel as by the wax, which is why size mix is a cost decision and not only a marketing one. Second, the wax line at 800 candles a month is 104.40 kg, which is more than ten of the largest pack the store lists. CSI 464 is sold in 500 g, 1 kg, 5 kg and 10 kg on the site; above 10 kg in one consignment, ask on WhatsApp +91 7397976926. A plan that assumes you can click one button for 100 kg will need a phone call.

Build this table from your own despatch records, not from your intentions. Take the last three months, count candles by size and by scent, and use the busiest month rather than the average — a plan built on a quiet month fails in a busy one and you will not notice until you are short. If you have fewer than three months of history, use your best month and revise it in four weeks.

Step 2 — Cover targets, set by consequence rather than price

Every material on the sheet sits somewhere on two axes. The first is what a shortage does: some stop a pour outright, some merely slow it, and one or two only delay despatch. The second is what holding it costs: a hundred wicks and a hundred jars occupy similar shelf space and differ by a factor of eighteen in money. Cross those two axes and the cover target almost writes itself, which is what the diagram above sets out.

The interesting cell is the cheap-but-critical one. Ten weeks of wicks and twelve of wick stickers and care stickers at 400 candles a month is ₹9,891.20 altogether — about a fifth of what four weeks of vessels costs, for two and a half times the protection. There is no reason to be careful with those lines, and a great deal of reason to be careful with glass. Small manufacturers routinely get this backwards, ordering wicks in hundreds because the packs are small and glass in hundreds because the price per unit looked reasonable.

Step 3 — What the plan asks for in cash

A plan that nobody has costed is a wish. Applying the cover targets from step 2 to the three output levels from step 1 gives the amount of working capital the plan actually asks for — and the number grows faster than most makers expect, because two of the seven lines scale with output and cost real money per unit.

Three readings come out of that table. First, the plan roughly doubles as output doubles, which is unremarkable — but it means a manufacturer stepping from 400 to 800 candles a month needs to find roughly ₹97,117.35 of additional working capital for materials alone, on top of any equipment. Second, vessels are consistently the largest single line at every level, which argues for buying glass closer to the pour than wax. Third, the wick and sticker lines stay tiny even at 10–12 weeks of cover, which is why they should never be the thing you economise on.

Two honest caveats. The table is materials at cost, so it is not the value of your business and it is not a budget — it is the cash you will not be able to use for anything else while the plan is running. And it assumes you pour what you plan. The fastest way to destroy a working-capital plan is to hold stock for products you have stopped selling, which is what the quarterly and annual reviews below exist to catch.

Step 4 — The rows that must stay blank

Manufacturing a candle costs more than the materials in it. Every maker knows this, and it is precisely where supplier guides start inventing. CSI sells wax, fragrance, wicks, vessels, colour, finishing items and tools, so those can be priced from live stock and checked by anyone. It does not sell cartons, mailers, printed labels, ribbon, shrink wrap or courier services, does not publish freight rates, and has nothing to say about your rent, your electricity or your own hours. Those belong in the plan, with no number in them.

One further boundary, and it belongs to your accountant rather than to your stock sheet. Prices on the CSI store are inclusive of tax, as stated on the Luxury Soy Wax Chunks page, and GST invoicing is available on request. What your own tax position is, what you can claim, and what registrations your output level requires are questions for your own adviser, not for a supplier's blog. Keep the plan to quantities and material cost and it stays useful to anyone, at any scale, anywhere in India.

Step 5 — The review rhythm that keeps the plan true

The festive adjustment, and storing what you have bought

Diwali 2026 is 8 November 2026. Soy candles keep developing throw for 14–21 days — the Luxury Soy Wax Chunks page recommends curing ideally 1–2 weeks before burn testing — and finished stock still has to reach buyers, so production for the festival wants to be complete by about mid-October. The consumption peak therefore sits in September and early October. A manufacturer at 400 candles a month who expects to treble output for the season needs roughly ₹79,458.84 of wax for that block alone, and the whole plan at double its normal cover is about ₹1,94,234.69.

The right way to absorb that is narrower rather than bigger. Cut the festive range to the three scents that sell, so the extra oil goes into depth rather than breadth. Lift cover on the four lines that stop a pour and leave the rest alone. Place the ramped orders as two consolidated consignments in September rather than six small ones in October. And then let the cover fall back in November instead of carrying a festive shelf into a quiet January.

Storage is part of the plan, not an afterthought

Holding more stock in Indian conditions is a physical problem as much as a financial one. Delhi, Ahmedabad and Nagpur run past 40°C for weeks, and an uninsulated store room will soften wax long before the season ends; monsoon humidity in Mumbai, Kochi and Kolkata is hard on cardboard and on anything with a paper label. The CSI 464 page gives a shelf life of 60 months in cool, dry storage, away from sunlight and moisture, and the Premium Coconut Soy CSI 468 page the same with a note to keep it sealed. Those are generous numbers under the stated conditions and meaningless outside them.

Three practical consequences for the plan. Keep sacks off the floor and away from an outside wall. Keep fragrance bottles closed, upright and out of direct light — oil is the most valuable thing per kilogram on your shelf and the easiest to spoil through carelessness. And cap the cover on glass not only by cash but by the space you can actually store safely: stacked cartons of jars in a narrow workshop become breakage, which is the one inventory loss that turns into a customer problem.

Where inventory plans fail in real workshops

1. The plan counts packages instead of contents

An opened 10 kg sack with 4 kg gone is a 6 kg sack; a 100-wick bag with 22 left is a 22-wick bag. Keep opened stock physically separate from sealed stock and weigh the opened container during the weekly count. This one habit removes more surprises than any amount of forecasting.

2. Dead stock is never written down

A scent that stopped selling in March is still on the sheet in October at full value, quietly making the plan look healthier than it is. Once a quarter, mark anything that has not moved in three months and decide: pour it into a clearance size, blend it into a seasonal set, or accept the loss and stop reordering. A 500 g bottle of a scent nobody wants is ₹2,371.80 of cash pretending to be inventory.

3. The plan grows a second page

Once a sheet starts tracking lids by colour, ribbon by width and every mica shade, nobody updates it. The seven lines in this plan are the ones that stop production or move real money. Everything else can live on the fortnightly shopping list without a cover target of its own.

4. Equipment is confused with inventory

A Mini Electric Wax Melter at ₹2,360.00 or a pen thermometer at ₹354.00 is a one-off purchase that changes your capacity, not a line with a cover target. Keep equipment on a separate list with its own replacement schedule. Mixing the two makes both harder to read, and it is how a workshop ends up with three thermometers and no wicks.

5. Nobody owns the sheet

In a two-person workshop the count, the order and the recalculation often fall between the two people and land on neither. Name one person, put the weekly count in a calendar, and keep the sheet where the stock is rather than on a laptop. If you are planning a step up in output, scaling to 1,000 orders a month and the 12-month candle business calendar both deal with the rhythm around the sheet, and what it costs to start covers the equipment side.
